> Key: CASSANDRA-15133

> Restarting a node causes gossip generation update. When it propagates the message to the cluster, every node blindly update its local token metadata even it is not changed. Update token metadata is expensive for large vnode cluster and causes token metadata cache unnecessarily invalided.
